28906261 divided by 2 
We want to figure out the number of times 28906261 can be divided by 2.

Going ahead to step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Going ahead to step 2:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Going ahead to step 3:
2 goes into 9 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we take 8 away from 9, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Advancing to step 4:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1445.0
Deduct 10 from 10 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Let's proceed to step 5:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 14453.0
If we take 6 away from 6, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Let's proceed to step 6:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 144531.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Advancing to step 7:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1445313.0
If we subtract 6 from 6, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Going ahead to step 8:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 14453130.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14453130.5
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14453130.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 14453130.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 14453130.5 with a remainder of 0.0.
